Non-sKInABLn TIRE GUARD. i

Specificationof Letters Patent.

Application filed anuary 11, 1912. Serial No WlLF Z l.

To all whom it may concern Be it known that I, LORENZO CiArroNE, a

' subject of the King of Italy, residing in the to be used on the higher class of vehicles.

Its objects are, to provide means effectually preventing puncturesin such tires and the consequent bursting thereof, to minimize the wear of the same and which will prevent side-slipor skidding; moreover its object is to prevent a tire from coming off 1 the. wheel of a vehicle by accidental displacement and yet in no manner to interfere with the proper resilient action of such tires; and finally, to provide such guards so constructed that sections thereof may be removedor replaced without disturbing the remaining sections, thereby greatly facilitating its application.

These and other objects, which will be-' come more fully apparent, are attained by the novel arrangement and construction of parts hereinafter fully described and shown in the accompanying drawings, forming parts of this. specification, and in which:

Figure 1 is a side view of a wheel having my guard applied.

ig. 2 is av partial sectional view, taken on line 22'of Fig. 1.

Fig. 3 is a perspective view of the guard in detail and Fig. 4 is a detailed view showing more particularly how the hooked links are engaged with the holes inthe extensions of the tread plates.

As much. of the expense attendant upon operating vehicles using tires of the character described is caused by the rapid wear and deterioration of the outer or contacting surface, causing frequent renewal of the same; many protective devices have been proposed; some of these have, also been ar- 5% ranged with the view of avoiding skidding or side slipping, as the result of such action is not only highly destructive tothe tires but uses the energy-pf the motive power uselessly and is productive of many accidents resulting in damage to the vehicle and those using i In order toovercome these troubles, and at thesame time fully preserve the resilience, of the tire, I- have devised :a guard com prised of a series of segmental plates 10 shaped to agree with the tire profile in cross Patented A r. a, tort;

section and having on" the outer surface raised projections 10 which may be of any L preferred size or shape to suit the conditions of use; each of the plates are provided with ears or extensions 11, at both ends, on each side near their inner edges; these extensions have holes 12 formed in them.

adapted to receive hooked links.13 pivotally connected by the members let'insuch manner that each plate is maintained at a; definate distance from the adjacent plate, but

yieldingly, so that each plate is-free to adjust itself to. the tire and inequalities ofthe road bed or surface conditions; these links prevent longitudinal displacement, one plate with respect to another, and also creeping around the surface of the tire.

In these holes12 are also inserted hooks 15 to which are attached short chains or other equivalent flexible connecting means 16 those. belonging to adjacent plates being brought together at their inner endsand engaged by an eye-bolt 17, the same being screw-threaded and provided with a nut 18 for adjusting the tension of. the chains, and through them secure the plates 10 tightly. upon the surface of the tir In order to maintain a uniform degree of tension all around the tire, the shanks of the eye-bolts 17 pass through rings-19 disposed sections 19, 19" and 19", each section being united by a hinge joint 20 so constructed that upon the withdrawal of a single bolt member 21 the joint may be opened freely and without interference with the other sections of the ring except that the stress is incidentally relieved onthe remaining engaged bolts.

From the foregoing it may be seenthat this device can be readily applied to anyordinary form of rubber tired vehicle wheel Without involving any changes in it or previous preparation whatever; that it avoids the weighty and cumbersome appearance of devices used for similar purposes and has the feature of automatic "adjustability so pronounced that a novice can successfully mount and put it in operation.

- Having thus described my invention, What I-claim asnew and desire to secure by Letters Patent, is: y

In combination With a tire, a guardthere for comprising a plurality of tread plates shaped to conform to the transverse configuration of said tire and disposed upon the periphery thereof, links flexibly connecting the tread plates together, a floating Copies of this patent may be obtained for retaining device, adjustable means carried by said retaining device, and connecting devices arranged in pairs between said adjustable means and the tread plates, the connecting dei ices of each pair being attached at one end to a common point on the adjustable means While the other ends of said LORENZO CIAFFONE.
